Exam 26: Quantum Physics and Atomic Structure

A compact disc of a CD player has a moment of inertia I = 2.5 × 10^-5 kg · m² and rotates at 500 rev/min. Taking L = Iω and using the quantization of angular momentum, the approximate value of n is = 1.055 × 10^-34 J · s)

Which of the following formulas has the correct units for the linear momentum of a photon?
